Forum: GratefulDead Subject: Re: TLH: Questions on verifying checksums

The 2 checksums in one folder makes some sense as I experienced that (and I was mixing things up; it was a GD show not P&F so that one show seems to be okay now in my mind).

This show below, however, just has one checksum and I got the same message. I decoded to .wav to give it a listen and it sounded fine though maybe the errors aren't easily detectable? any thoughts?

Thanks all for the advice/help/teachings. Have a good week.

well, you've actually come across an archive source (the 3/10/00 P&F show) that won't check via TLH, however, the flacs do match the .md5, which you can manually check by creating an .md5 checksum in TLH (the results will appear in the window of TLH), and visually matching with with the .md5 signatures in the checksum that you downloaded with the fileset (you can view the contents of the .md5 by changing the file extension to .txt and opening in whatever text reader is on your computer)

i have found that in these instances, i was able to verify the .md5 by verifying with mkwACT (the common predecessor to TLH), but i no longer have mkwACT on my computer

at the end of the day, these instances don't happen all that often, i'd even say rarely, and pretty much only with these older filesets, for whatever reason

i also wouldn't be concerned if you come across an instance similar to this in future, where the entire fileset does not check; if it were just one or two files in the fileset, then i would just re-download those files, but that is not the case here

the checksums exist so that anyone can confirm that they have the exact fileset as determined by the unique shnid # maintained by the db.etree database, as well as to verify the integrity of the download; while acknowledging the importance of maintaining a digital signature for circulating filesets, especially in terms of what is shared online via direct download here at the archive or certain bit torrent sites, at the end of the day, 99% of the people who receive the music, just care about the music; for what it's worth, for many GD shows i've downloaded here at the archive, i've modified the files (renamed, added metadata, ect), thereby making the original checksums useless; rest assured, i'm not losing any sleep over it

you're very welcome, glad i can lend what small amount of knowledge i've picked up over the past several years; and believe me, when i was just discovering/finding out about .shn/.flac/.md5/.ffp, and all the correlating processes, it was both fun and frustrating at the same time; cheers
